To allwhomctmayconcem:

Be it lmown that I, Hman S. Kmmonn, a citizen of the United States, residing at Eldon, in the county of Miller and State of Missouri, have invented certain new and useful Improvements in Photographic-Film Holders, and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the am nexed drawings, making a part of this s iication, and to the letters and figures o reference marked thereon.

The object of my invention `generally stated, is to provide a frame or hol er of ineensive character which will, nevertheless, e

ciently perform its function for holding cut ilms to support the same in a tank, jar, or other receptacle containing developing iluid, and to this end my invention consists in the holder constructed substantially as hereinafter specified and claimed.

In the accompanying drawings,-

'Figure 1 is a perspective view of an embodiment of my invention in which a number of frames yare joined together in a. sort of cage to enable the simultaneous submerene of a number of films in the developing Fig. 2 is a vertical section through the same;

Fig. 3 is a perspective view of a frame or holder for suspending a single iilm in the developing duid;

Fig. 4 is a detail cross section on the line 4-4 of Fig. 3;

Fig. 5 is a similar view of one of the lower',A

corners of one of the frames to show the drainage hole thereat.

I provide a frame into which the film may be inserted and removed by sliding motion, which is of rectangular form, corres onding in form and dimensions with the and which supports the film at each of its four edges, its support at each side and at the bottom being in a groove or channel and its support at the top being between a pair of light bars that are spaced apart, so that the film may be slid between them in being placed in the frame and in being drawn therefrom. The bottom and side bars 10 of the frame are U-shaped in cross section, and some light and inexpensive sheet metal'is employed in making them, and at each of the lower corners where the side and bottom bars join, a slot or hole 11 is out through the corner to allow the drainage of the Huid from the frame. The top of the frame in the individual form or the form for holding a e lilm,lshown in Fig. 3 consists of two pa e1 light strips 12 and 13, separated by a ace permitting passage between them of a liln, and one of w ich projects higher than the other, so as to afford a guide surface for the ready insertion of the film into the frame, and for lthe engagement of a suspending hook, that has a horizontal tongue 14, that passes through a perforation in the higher strip 13 above the stri 12. Said hook has two arms, one of whic carries the tongue, while the other has an eye 140 that passes over the free end of the tongue, the two arms joined by a spri coil 14 intermediate eir ends, and whic normall holds the eye over the tip of the tongue. ne of the hook arms is downturned at its up er end for providing the hook member 41 for catching over a wire or other suitable sup-- ort.

p In the form of my invention shown in Figs. 1 and 2, where a collection of the frames for the simultaneous handling and development of a number of films is illustrated, the frames are joined together on their outer sides near top and bottom by suitable attachment to cross strips 15, and at each of the four corners there is a vertical stiiening post 16, the bottom of each of which is extended slightly below the collection of frames so as to form a supporting foot or leg. The tops of the frames in this case are formed by cross bars 17 that in cross section are substantially inverted V-shaped, the legs of a bar being respectively attached to the adjacent sides of adjacent bars of a frame. Thus, the spaces between adjacent bars are bridged over, and an unobstructed space left in vertical alinement with the ves of the side bars themselves, and the inclined surface formed by one of the legs of the V constitutes an excellent guide for directing each film into its appropriate holder; or to ut it in a different way, an outwardly flaring or diverging guide way is provided by adjacent cross bars 17 for easily directing the film in the frame grooves. The cross bars at substantially mid-length have notches 19 in their u per sides which expose the top edge of the lms when in the frames so that they may be readily grasped for lifting out of the frames.

It will be noted that ywhether the cross bars have the form shown in Fig. 2 or that shown iniFig. 3, the pair that connect thev side bars of the frame and form the guide at the top of the latter areattached to the inturned portions ofl each side bar and thus a. stiE or rigid construction is provided.

The films, when placed in the collection of frames as shown in Fig. 1, are held therein at the top by a plate 20, which is of a size to completely cover the to s vof the films, and at one end is' connecte by a hinge 21, while at its other end it has a tongu is engaged by a sprin latch 23. Pivotally connected to ears ont e top of said plate is a wire` handle 24 by which the collection of frames and the films therein may be suspended. It will be observed that when the cover plate is in its closed position, the collection of films may be inverted or'put in any position without any danger of slipping or sliding out of the frame. l

It will be observed that with my invention, there are no projections on the exterior of the hanger and hence, there is no danger of catching on the sides of the developing tank when the hangers are lowered therein, and hence, no traps for bubbles of air enggering the formation of air bells onthe Thel single frame or holder of the construction shown in Fig. 3 with the suspending hook omitted will fit the plate cage of the Eastman plate tank or any other similar i tank for holding plates, it being necessary merely to insert the film in the holder and to hold the same in the plate cage just as in the case of a plate. The suspending hook enables the holder with the film to be suspended in any tank or receptacle and fo'r olding the lm to dry either in or out of the holder,the ilm when out of the holder being engaged by the horizontal tongue 14, which is sharp so that it will readily penee 22- that 'respectivel vtions of t e two vframe sides and spaced trate the film andA its projtecting sharpened end will be en by t e yeye Aon one of the hook arms. I the form of my. invention shown in Figs. J and 2 which embodies a number of holders, the same t in an Eastman late tank in place of the late cage provi ed for use withsuch t and the same canbe suspended inl any tank or receptacle. It will be observed that no vextra lo device is required.

Havmg described my invention what I claim is,- v v 1. A holder for photographic films for developing the same, comprising a rectangular frame whose sides and bottom are of sheet metal and V-shaped in cro' sectin, and whose top consists of parallel strips spaced apart, and forming a guide for the insertion of the film into the frame, said strips being attached to the inturned porapart to form' o po'site film guiding surfaces.

2. A holder or photographic films for developing the same, comprising a plurality of frames each having sides and a bottom with Iilm edge receiving grooves and a top formed of cro bars of substantially invertcd V-shape in cross section, each bar between the vextreme outer frames lying between and connecting. adjacent frames.

.3. A holdery for photographic films for developing the same, comprislng a plurality of frames each having sides and a bottom with film edge receiving grooves and a top formed of cross bars of Jsubstantially -inverted V- shape in cross section, each bar between the extreme outer frames lying between and connecting adjacent frames, the holder having a movable cover plate for the spaces between said cross bars.

In testimony whereof I aiiix my signature.
